SPACE-AIDJ'US'lING"` MEANS FOR GROUND-ENGAGING IMPLEIVIENTS. y

Application filed July 16,

This invention has reference to an adjusti suitably, it being understoodthat generally the rows are practically parallel as compared with eachother and that the implements should remain approximately parallel withthe rows while moving forwardly. One of the objects of the invention isto provide means for the foregoing purposes which will consist of fewand simple parts so that manufacture will be practical and economical.

'Ihe invention consists of the new and useful construction, combinationand arrangement of parts as described herein and claimed, and asillustrated in the accompanying drawing, it being understood thatchanges in form, size, proportion of parts and minor details may be madeas found to be convenient, said changes being determined by the scope ofthe invention as claimed.

In the drawing, Fig. 1 is a plan view of the device. Fig. 2 is asectional view on line 2-2 of Fig. 1. Fig. 3 is a view showing themounting of a radius rod upon a drag-bar and the supporting-plate of .aground-engaging implement. Fig. 4 is a rear view of the drag-bar. Fig. 5is a front view of the dragbar. Fig. 6 is a plan view of a casting orcoupling-member employed. Fig. 7 is a side view of the casting. Fig. 8is aside view of a pull-bar. Fig. 9 is a side view of a radius rod andan eye-bolt. j

Referring now to the drawing for a more particular description, numeral11 indicates a drag-bar preferably constructed of angleiron, upon itshorizontal flange 12 being mounted a suitable tongue 13, the verticaliiange 14 of said drag-bar being provided with apertures arranged ingroups, the apertures for each group being uniformly spaced apart andindicated at a, b .and c, best shown in Figs. 4 and 5 of the drawing.

Numerals 15 indicate brackets or aper- 1925. Serial No. 43,978.

tured castings, each having a iange CZ. By means of bolts 16 thecastings may be se-l cured to the flange 14 of the drag-bar, and, as isobvious, the castings may be disposed nearer together or further fromeach other, as may be required.

Numerals 17 indicate supporting-plates, preferably constructed of angleiron, and the horizontal iiange e of each plate 17 is secured to aground-engaging implement 18.

While I yhave shown each of these implements 18 to consist of a pair ofopposed discs 19 connected by a shaft 20journalled in an arm 21 which issecured to a plate 17, these parti-cular features are not important,

andV I may employ any suitable ground-l engaging implements to-worl; atthe sides or between the rows, the object of the present invention,broadly, being to provide means for making adjustments so that theimplements may be disposed at suitable distances from each other,corresponding to the transverse distance between the rows, whet-her wideapart or narrow, and also to provide means for maintaining theimplements parallel with the line of travel during the forward movementof the drag-bar, and thereby preventing any transverse swingingmovements of the implements.

The vertical anges f of the supportingplates 17 are preferably provided,midway between their ends with apertured castings 22 or brackets similartothe castings 15. Numerals 23 indicate draw-bars, each preferablyhaving upset end-port-ions g, said bars being for the purpose ofconnecting the implements 18 with the drag-bar 11, their end-portions gbeing disposed in the apertures of the castings 15 and 22.

Numerals 24 indica-te radius rods, each being connected with thedrag-bar 11 and to an end-portion of a' supporting-plate 17. Vhile Ihave shown each ofthese rods to be provided with an upset end-portionadapted to be received by an eye-bolt lc which is mounted in thevertical fla-nge of the drag-bar, the opposite ends of the radius rodsbeing secured to the vertical flanges f of the supporting-plates 17,these particular features are not important, but are preferred for thereason that they facilitate the operationk of making adjustmentsconveniently and readily.

The function to be discharged by each radius rod is to prevent anytransverse 'swinging movement of a supporting-plate 17 llO to bedisposed nearer together or further `iiiioijn ieach other, as required.di

While in the presentl instance only three implements are shownattachedhto thevdragbar, a greater or lessernumber ,obviously could beused. making the adjustments, after the bolts 16 and have been removedfron theirA apertnresthey ma; 4be inserted in apertures "of the gronpsshown in Figs. and 5to canse incieasieor,decrease in the vdistance .from(eachother ofthe bars 23, no
